This colourful ombre effect can be replicated at home in your choice of colours. OPI nail expert Cheryl Cooke used the sponge technique she outlines here at the Designer Selection shows at Fashion Week, using two colours for simplicity’s sake. She paired the lolly and lipstick pink shades called OPI Suzi Shops and Island Hops and Suzi Has a Swede Tooth for a tonal effect rather than a contrasting trio of shades as shown above.
